The noise you hear is valve clatter. You should not adjust your timing chain. Instead get a manual and find the vlave clearances for that bike. (Ex. The exaughst valve may be .006" and the intake valve may be .004") Then you'll need a feeler gauge, and to do this you'll remove the valve covers and get the engine to TDC (Top Dead Center) This is where the piston is at the very top of it's stroke and both valves are shut. (compression stroke) You must then loosen the rocker arm nut to the point that you can insert the feeler gauge between the rocker arm and the top of the valve run the nut down tight to the feeler gauge and then pull gauge out and repeat on the other valve.
